摘要： PURPOSE:To prevent occurrence of an offset in tracking error signals and enable generation of good focus error signals by providing a device that generates focus error signals by a difference signal between a sum signal of output signals of the first and third, and the second and fourth photoelectric elements. CONSTITUTION:If S1-S4 denote output signals from photoelectric elements PD1-PD4 constituting a light receiving section PDA, the focus error signal Se can be determined by an expression (1) using output signals S1, S2, S3, S4 of four photoelectric elements PD1, PD2, PD3, PD4. Se=(S1+S3)-(S2+S 4)...(1). The focus error signal Se shown by the expression (1) is considered as a positive signal when the position of the signal face of a recording medium 7 is off from the focus position of a condenser lens 5, and considered as a negative signal when the position of signal face of the recording medium is nearer then the focus position of the condenser lens 5. By driving and controlling the condenser lens 5 by an actuator, good focus conditions can be obtained at all times.

摘要： PURPOSE:To permit the stable superfine work by axially supporting a main shaft installed in free displacement in the axial direction onto a magnetic bearing as a thrust bearing and allowing the minute displacement in the axial direction by controlling the voltage or the electric current applied onto a coil. CONSTITUTION:When the edge surface 10a of a workpiece 10 is cut, a tool installation board 22 is roughly shifted in the direction of arrow X1, and cutting is performed so that the working dimension of the workpiece 10 becomes T+DELTAT. Therefore, the final finishing dimension T is obtained by the cutting work by a minute cutting-in amount DELTAT. Said minute cutting-in amount DELTAT is set so that a magnetic field is generated by the voltage or the electric current applied onto a coil 27, and a magnet 24 is repelled or attracted to a magnetic bearing 23 by the magnetic field of the coil 27. In other words, the transfer amount of the workpiece 10 due to the magnetic field of the coil 27 becomes the relative cutting-in amount of a cutting tool 21 for the workpiece 10. Therefore, in this method, cutting work is stable for the temperature variation, and is not influenced by the external turbulence such as the cutting resistance and the vibration supplied from a driving source, and the stable superfine work is permitted.

摘要： PURPOSE:To simplify the constitution of an optical system and reduce the cost by holding the oscillation wavelength of a semiconductor laser constant by a waveform control loop which uses an optical filter having such a transmission characteristic that light varies sharply in transmittivity to the optical wavelength. CONSTITUTION:When the oscillation wavelength of the semiconductor laser 2 is made smaller than a specific value lambda1 owing to, for example, a drop in room temperature, the mode of projection light from a filter PF1 which has transmission characteristics as shown by a curve A is asymmetric about a horizontal axis as shown by a curve 5. A filter PF2, on the other hand, has modulation characteristics as shown by a curve B. Therefore, the synthetic modulation mode of the filters PF1 and PF2 to laser light is asymmetric on a horizontal axis as well. Such a signal is extracted by a filter 14 and detected by a detecting circuit 15 to generate a DC component. The DC component is supplied to a Peltier element 13, which is heated, so that the wavelength of the laser light returns to lambda1. Thus, the oscillation wavelength of the laser is held constant by the simple constitution of the optical system.
摘要翻译：目的：为了简化光学系统的结构，并且通过使用具有透光特性的光学滤波器的波形控制环来保持半导体激光器的振荡波长恒定，从而降低成本，光传输特性使得光的透射率与光波长变化很大。构成：由于例如室温下降使半导体激光器2的振荡波长比特定值λ1小，具有如曲线A所示的透过特性的滤波器PF1的投影光的模式如曲线5所示，关于水平轴是不对称的。另一方面，滤波器PF2具有如曲线B所示的调制特性。因此，滤波器PF1和PF2对激光的合成调制模式是不对称的水平轴也是。这样的信号由滤波器14提取并由检测电路15检测以产生直流分量。将DC分量提供给被加热的珀尔帖元件13，使得激光的波长返回到λ1。因此，通过光学系统的简单结构，激光器的振荡波长保持恒定。

摘要： PURPOSE:To reduce the moment of inertia of a moving part and to eliminate the need for an operating circuit by constituting the moving part to drive two- dimensionally a reproducer stylus with a prescribed number of coil, a cantilever and a linking section only. CONSTITUTION:The moving part driving two-dimensionally the reproducer stylus 12 in the direction of a track of a disc D and a direction orthogonal to it, is constituted only of the cantilever 13, a linking pin 15, the 1st coil pair of coils 4, 5 and the 2nd coil pair 6 only. Thus, the moment of inertia of the moving part is decreased and the tracking characteristic of the stylus 12 is improved. In impessing a tracking control signal and a time axis error correcting signal to each of the coil pairs, the constitution is not complicated not by using an operating circuit, and the reproducing stylus is driven two-dimensionally to attain the excellent information reproduction.

摘要： PURPOSE:To put a compact disk to practical use, by using a platelike member which is long in the direction orthogonal to a crossing direction of a recording track, and is parallel to a signal face of a disk, in the middle part of at least one arm member. CONSTITUTION:As for an arm member constituted of a damper 30 and a blade 32, the blade 32 which is long in the Y axis direction orthogonal to a crossing direction of a recording track of a signal face, and is parallel to a signal face of a disk is used. Accordingly, a range in which a side wall 26 and a bracket 29 move relatively in the Y axis direction is a deformed portion generated by shearing deformation of the damper 30. Therefore, a movement of a housing of an optical system in the Y axis direction becomes a minute extent that can be disregarded. Accordingly, it is possible to generate no offset in an optical spot for reading a signal, therefore, it is possible to put an optical pickup device to practical use to a compact disk having a small diameter of the innermost circumference of a recording track of an information signal.
